We maintain genuine component inventory and follow ELPAC technical documentation to restore full operational performance.
Expert ELPAC power supply and embedded system repair across all product lines.
ELPAC Product Lines We Repair
Our engineers are trained on the full ELPAC product range. Below are the major product families we service.
EA-Series Industrial AC-DC Power Supplies
Single and three-phase input, 50-3000W industrial-grade power supplies with wide-range input tolerance and active PFC. Common faults include capacitor drying, FET thermal failure, and input relay chatter under voltage sag conditions.
HOP-600/1000 High-Reliability Open-Frame PSUs
Fanless, potted open-frame designs for extreme temperature and vibration environments. Frequently encounter thermal runaway in coastal or high-humidity installations due to electrolytic capacitor deterioration.
ELC-Series Medical-Grade Isolated Power Modules
Ultra-compact DC-DC converters with reinforced isolation for medical and HVAC control systems. Repair focus on isolation winding shorts, output capacitor ESR rise, and solder joint fatigue from thermal cycling.
PB-Series Enclosed Industrial Power Boxes
Modular enclosed PSU systems with integrated PFC and monitoring interfaces for factory automation. Typical failure modes include cooling fan motor bearing wear and bridge rectifier diode leakage.
PWM-Series DC-DC Converter Modules
Plug-in and solderable DC-DC buck and boost converter modules for distributed power architecture. Common repair issues: PWM control IC failure, inductor core saturation, and output feedback network drift.

Common ELPAC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ELPAC equipment arriving at our workshop.
- ✓Electrolytic capacitor drying and ESR rise — ELPAC industrial PSUs operate in high-ambient-temperature factories across Indian regions. Electrolytic capacitors in the primary filter stage age rapidly, leading to elevated equivalent series resistance (ESR), output ripple surge, and eventual bulk capacitor thermal runaway.
- ✓FET or MOSFET thermal failure in switching stage — ELPAC converter FETs experience gate-source leakage and thermal drift under sustained overload or ambient heat stress. Indian plants often run equipment beyond rated duty cycle in monsoon or summer peak conditions, accelerating FET degradation.
- ✓Input relay chatter and contact erosion — ELPAC input relay stages experience contact pitting when subject to voltage sag or phase loss conditions common in older Indian industrial facilities. Relay contacts weld or erode, creating intermittent mains connection and random shutdown events.
- ✓Transformer primary or secondary winding short — ELPAC transformer insulation degrades due to sustained thermal stress, moisture ingress, or impulse overvoltage transients. Indian manufacturing plants with poor surge protection or unstable grid voltage experience winding insulation breakdown and turn-to-turn shorts.
- ✓Output regulation drift and load-line instability — ELPAC feedback amplifier components (op-amps, zener diodes, feedback resistor networks) drift over time due to aging and thermal stress. Output voltage creeps upward or sags under load, affecting downstream PLC and servo drive operation.
- ✓Cooling fan motor bearing wear and fan speed loss — ELPAC enclosed PSU cooling fans (in PB-Series units) accumulate dust and vibration damage in Indian textile mills, foundries, and cement plants. Fan motor bearings wear, reducing airflow and causing secondary thermal failures in power stage components.

Frequently Asked Questions — ELPAC Repairs
Do you repair ELPAC equipment anywhere in India?+
Yes. Synchronics repairs the complete ELPAC product range — AC-DC power supplies, DC-DC converters, medical-grade PSU modules, and embedded power systems. We offer pan-India pickup and delivery from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bengaluru, and all other major cities. All repairs are executed at our fully equipped facility in Vadodara, Gujarat, with TAT of 5-7 working days for standard fault diagnosis and component replacement.
What ELPAC power supply models does Synchronics repair most frequently?+
The EA-Series industrial AC-DC supplies and HOP-Series open-frame PSUs represent the bulk of ELPAC repairs in Indian plants. We also regularly service ELC-Series medical-grade modules used in HVAC automation, and PB-Series enclosed power boxes deployed in textile mill and foundry automation racks. Our engineers are trained on the full ELPAC model range and maintain schematic documentation for all variants.
How do you diagnose ELPAC power supply faults without obvious physical damage?+
Synchronics uses precision benchtop test equipment to measure input voltage range, output voltage regulation, ripple and noise levels, thermal response under variable load, and insulation resistance across all active channels. We perform hypot testing on AC input stages and dielectric strength checks on isolated modules. Any fault identified is documented on a detailed repair report with before/after measurements, helping you understand the root cause and preventing recurrence.
Can Synchronics provide warranty on ELPAC power supply repairs?+
Yes. Synchronics provides a 12-month parts and labour warranty on all ELPAC repairs, covering the same faults or related component failures. If a repaired ELPAC PSU fails due to our workmanship within the warranty period, we repair or replace it free of charge. Warranty terms apply to normal operating conditions within the PSU's rated input voltage, ambient temperature, and load specifications.
What is the cost range for typical ELPAC power supply repair versus replacement?+
Most ELPAC repairs cost 30-50% of a new unit, depending on the failure mode. Capacitor replacement, FET/diode substitution, and feedback network recalibration typically run Rs 8,000-15,000 for EA-Series and HOP-Series units. Major faults requiring transformer rewind or full control board replacement may approach 55-65% of new unit cost. Contact Synchronics for a free quote after initial fault assessment. Many Indian plants choose repair to reduce downtime and environmental impact of e-waste.
How do I send my ELPAC unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a ELPAC drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on ELPAC repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your ELPAC unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
